ROCK-CRUSHER.

SPECIFICATION forming part of Letters Patent No. 320,559, dated June 23, 1885.

Application filed February 12, 1885. (No model.)

To all whom, it may concern.-

Be it known that I, Gonnnmus W. HUSON, of Veaverville, county of Trinity, and State of California, have invented an Improvement in Rock-Crushers; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to a new and useful rock-crusher; and it consists in the combination of devices which I shall hereinafter fully describe and claim.

The object of my invention is to provide a simple rock crusher or breaker, the greater part of which, being of plain timbers, is adapted to be constructed and used with advantage at small mines and out-of-the-way places where it would not be advisable to transport more expensive and elaborate machinery.

Referring to the accompanying drawings,

Figure 1 is a perspective view of my rockcrusher. Fig. 2 is a vertical longitudinal side elevation of same, a portion of the flange of the bed being broken away to show the die within.

2 A are the mud-sills, made of plain timbers and laid parallel. B are cross-sills of similar nature mounted on sills A. The middle one of the crosssills has bolted to its center the bed 0. This consists of a metal piece the face of which is concaved longitudinally and its sides provided with upwardly extending flanges or guards c.

D is the die, also of metal, and having a convex face. Both bed and die are provided with 5 suitable shoes, or, for the sake of durability.

The convex face of the die is made on a curve having a shorter radius than that of the curve on which the concave face of the bed is formed, as shown in Fig. 2, whereby when the die is at rest in the bed it bears on its center, its ends being separated from the ends of the bed by reason of a divergence in the curves of the faces. There is thus left or formed spaces a at each end between the bed and die. The die D has a width just sufflcient to permit it to lie snugly between the side flanges of the bed, and it is provided with upwardly-extending flanges d, by which it is bolted to the block E, the flanges being let in to lie flush with the sides of the block. This block is bolted to a .beam F and the bed and die.

'sidewise from the rock-beam are journals 0,

long timber or beam, F, which is raised high enough to permit the interposition of screens G at the ends of the bed and die without interfering with them when said beam is rocked. To the center of the beam F is bolted solidly a standard, H, from thetop of which extend solid braces I to the ends of the beam. From the base of the standard extend diagonal braces J to the centers of braces I, whereby the whole frame is made rigid.

K is a water-wheel or other suitable source of power, having crank-pin it, from which a pitman, L, extends to the top of the standardH. Upon the ends of beam F, I may placeboxes BI, filled with rocks and serving as couuterbal ances. Upon the ends of the cross-sills B are laid beams N, parallel with the mudsills, and acting as side guides or guards for the rock- Extending which lie loosely in bearings I? on the side beams, N. These journals do not mount the rock-beam, which has its pivotal action in the bed, but simply act as safeguards against any tendency of said beam to slip in its bearing in the die. In the side beams, N, are made feed apertures or hoppers a, which slope downwardly and inwardly, and terminate just at the tops of the side flanges of the bed and near their ends, whereby the rock is adapted to be delivered by falling over the flanges directly into the sides of the end spaces, a, between the bed and die. Outside of the screens G are discharge chutes Q which emerge through the spaces between the cross-sills B. The operation of my crusher is as follows: Through the pitman L the standard H is rocked, thus rocking the beam F and die D. The rock is fed in through apertures n, and is deposited in the spaces a, between the die and bed, and is there crushed. Passing thence through the screens, it runs into and is discharged by the chutes Q.

It will be seen that the whole machine is simple in construction and inexpensive, being adapted for use anywhere, and efficient in its operation.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a rock-crusher, the concave bed 0, having the screen G at each end, in combina tion with the convex die D, the block E, to which said die is bolted, and the counterbalaneed rock-beam F, to which the block is attached, substantially as herein described.

2. In a roelccrusher, the concave fixed bed C, in combination with the counterbalanced rock-beam F, standard H, diagonal braces, the block E, secured under the beam, and the convex die D, secured to the block and resting in and tangential to the bed,substantially as hereby described.

3. in a rock-crusher, the mudsills A, crosssills B, and concave bed Con one of the cross sills, in combination with the rock-beam F, block E, convex die D, and the side beams, N, resting on the erosssills, and having feed apertures or hoppers n, communicating with the spaces at and between the ends of the bed and die, substantially as herein described.

at. A rock-crusher comprising the mud-sills A, cross-sills B, concave bed (3 on one of the cross-sills, the screens G at the ends of the bed, the rock-beam F, block -E, convex die D, resting in and tangential to the bed, the side beams, N, having feed apertures or hoppers n, communicating with the spaces at and be tween the ends of the die and bed, and the disel'iarge-chutes Q, communicating with the bed, the block E, to which the die is bolted,-

the rock-beam F, to which the block is secured, the screens G at each end of the bed and die, the feed apertures or hoppers n in the side beams, the discharge chute Q between the cross-sills, and the means by which the die is rocked, consisting of the standard H, the beam F, the pitman L, and means for operating the same, substantially as and for the purpose described.

I11 witness whereof I have hereunto set my hand.

CORNELIUS V. HUSON.
